Asp.net视图状态不保存控件的样式 [英] Asp.net Viewstate not saving a control's style

问题描述

我已阅读，在asp.net中存储视图状态在回发的控件属性的值。
可以说，我有一个具有一个文本框的网页

I have read that the viewstate in asp.net stores the values of control properties across postbacks. Lets say I have a page that has a textbox

<asp:TextBox ID="fldFileId" runat="server"></asp:TextBox>

，然后通过JavaScript客户端，我得到的元素的引用，然后设置边框样式正是如此。

and then on the client side via javascript, I get a reference to the element , and then set the border style thusly

refToTextBox.style["border-style"] = "dashed";

一旦回传，边框风格dissapeared与文本恢复到原来的样子。但对于一个asp的属性一眼：在VS2010的TextBox有是的一个边框属性它。
有没有为什么这个属性不被保存视图状态的一个原因？

Upon postback, the border style has dissapeared and the textbox reverts to its original look. But glancing at the properties for an asp:TextBox in VS2010 there is a 'BorderStyle' property for it. Is there a reason why this attribute does not get saved in the view state?

推荐答案

设置值的客户端不更新的ViewState。你必须设置样式服务器端的ViewState中存储它。或者，您可以：

Setting a value client-side does not update ViewState. You have to set the style server-side for ViewState to store it. Alternatively, you could:

1. 回发后重新运行你的JavaScript。


2. 店铺的造型在cookie中，并使用JavaScript来恢复风格。


3. <击>查找JavaScript库修改的ViewState在客户端（不推荐）。

1. Re-run your JavaScript after postback.
2. Store the styling in a cookie and use JavaScript to restore the style.
3. Find a JavaScript library to modify ViewState on the client-side (not recommended).
